WRAPPER FOR METAL SHEETS.

Specification of Letters Patent.

Patented Dec'. 24, 1907.

Application filed July lO 1905- Serial No. 268,901.

To all whom it may concern:

Be it known that I, HERBERT E. MARKS, of Poughkeepsie, Dutchess county, New York, have invented a new and useful l/Vrapper for Metal Sheets, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a perspective view of a package of tin plate constructed in accordance with my invention; Fig. 2 is an enlarged crosssection partly broken away showing the parts before the seams are closed; and Fig. 3 is a view similar to Fig. 2 showing the seam closed.

My invention relates to the packaging of thin metal sheets such as black sheets, tin

Heretofore these sheets have been packed in thin wooden boxes, which were nailed up in the ordinary manner.

My invention consists in doing away with the wooden box, and providing a sheet metal envelop or cover which leaves the ends of the pack of sheets open.

It also consists in providing a wire or other surrounding member which prevents endwise sliding of the sheets from the package; and further, in the construction and arrangement of the parts as hereinafter more fully described and claimed.

In the drawings, 2 represents the cover or envelop of the package. This consists of a wide sheet of iron or steel, which may be either black or coated. This sheet is bent to form the top and bottom and one side of the package, its ends 3 being reversely bent at the other side to form open seam portions. This cover or envelop is placed around the built-up pack of sheets to be shipped, and the seaming strip 4 havingbent-in flanges engaging the seam portions 3 of the cover is then slipped endwise into place, as shown in Fig. 2. The seams are then hammered down or otherwise compressed and a wire 5 is then preferably put around the package endwise and its ends twisted together as shown at 6 to prevent endwise slipping of the sheets from the pack. The package is then ready for lettering or marking and shipping.

From the foregoing description, it will be understood that the present wrapper is formed of a single metal sheet, the strip 4 constituting merely a seal rather than a side of the wrapper, for the reasonthat themturned free ends of the wrapper really constitute a side of the wrapper. By forming the wrapper in a single piece, said wrapperof itself constitutes at least two additional sides in the fact that the inturned free edges of the wrapper of themselves constitute one side of the wrapper and coine into relatively close mutual relation, whereby the connection between the ends of the wrapper is a single seam. Moreover, this seam includes a sealing strip which approximates the thickness of the package and of itself protects the folded ends of the wrapper.

The advantages of the invention result from the doing away with the use of wooden boxes and from the simplicity and cheapness of the package. The envelop or cover may be sheared up and used by the purchaser; and may be either coated or 'uncoated.

The cover may be made in two or more 1 side of the wrapper and then folded back.

across the outsl e thereof to form sealing wings, and a sealing strip having inturned edges embracing the sealing flaps substantially as described.

2. A rectangular wrapper consisting of a blank folded to form three sides of the wrapper, the free ends of the blank being turned inwardly to define the fourth side of the wrapper and then folded back across the outside thereof to form sealing wings, and a sealing strip having inturned edges embracing the sealing flaps substantially as described.

-3. A rectangular wrapper comprising a sheet metal blank folded to form three sides of the wrapper, the free ends of the blank being folded inwardly to define the fourth side of the wrapper and then folded back across the outside thereof to form sealing inturned edges embracing the sealing flaps,

the sealing strip and the flaps being pressed together to interlock them and connect the ends of the blank substantially as described.

4. A rectangular wrapper having opposite free edges turned inwardly and defining a side of the Wrapper and then folded back across the outside thereof to form sealing Wings, and a sealing strip having inturned edges embracing the sealing Wings and connecting the same by a single seam, the Width of the sealing strip being substantially equal to the width of the adjacent side of the Wrapper, substantially as described.

5. A rectangular Wrapper formed of a blank which is bent to form an end and opposite sides, the free ends of the wrapper being bent inwardly to define the other end of the wrapper and then bent outwardly to form sealing flaps, and a sealing strip having inturned edges embracing the sealing flaps and connecting the same by a single seam, the width of the sealing strip being substantially equal to the Width of the adjacent side of the wrapper, substantially as described.

In testimony whereof, I have hereunto set my hand.
